HONEYWELL MC-PDIY22 Digital Input Module

The HONEYWELL MC-PDIY22 is a high-reliability digital input module designed for integration with Honeywell Experion PKS distributed control systems (DCS), engineered to collect discrete digital signals from industrial field devices such as limit switches, push buttons, proximity sensors, and contactors. This module features 16 independent digital input channels with built-in optical isolation, which effectively suppresses electromagnetic interference (EMI) and ensures stable signal acquisition even in harsh industrial environments with high voltage fluctuations and electrical noise. It supports a wide range of input voltage levels, making it compatible with both DC and AC signal sources for flexible system configuration. Equipped with advanced diagnostic functions, the MC-PDIY22 provides real-time status monitoring of each channel, enabling quick identification of open-circuit, short-circuit, and fault conditions to minimize system downtime. Fully compatible with Experion PKS system components, it supports hot-swappable installation and maintenance, allowing online module replacement without interrupting critical process control operations. Widely applied in oil and gas, petrochemical, power generation, and manufacturing industries, this digital input module delivers a robust and cost-effective solution for discrete signal acquisition in industrial automation systems.

Important Note: The HONEYWELL MC-PDIY22 digital input module is exclusively designed for Honeywell Experion PKS DCS. Ensure proper channel voltage configuration and wiring polarity before system deployment to avoid module damage.
